Ever wanted to work a device that needs batteries, but the battery slot is too big for your batteries to fit? Well, here's a way to convert smaller batteries into larger batteries (in this case, converting AAA batteries into AA batteries).

Steps

1

Get your device that needs AA batteries and get your AAA batteries.

2

Grab some aluminum foil.

3

Place the AAA batteries into your device's battery slot. You will obviously see some extra space in the slot, since the AAA batteries are smaller than AA batteries.

4

Rip a piece of aluminum foil and curl it into a small ball. The size of the ball should be the same size of the extra space in your device's battery slot.

5

Place the aluminum foil in the gap. The aluminum foil should be on the battery's negative terminal, not the positive.
